Invention field
The present invention relates to sintered polymeric materials and production and preparation method thereof.
Background of invention
The tip or the nib of applicator (like e-Pointer, pen, applicator for cosmetics, medicine applicator etc.) are processed by felt or thermoplastic fiber materials (comprising nylon, acrylic acid or the like material (arylics) and trevira) usually.Tip or the nib processed by these materials have excellent mechanical intensity, therefore have higher resistance to fracture.And these tips or nib show the good fluidity of various liquid, and have snappiness, are applicable to make marks, write and other application.
But felt and fiber nib also have some shortcomings.One of them is when the felt of producing the required relative complex shape of various application and fiber nib, can have any problem.Another disadvantages associated is that felt and fiber nib can not be produced in a step.And multistep production has improved cost and the various designs that felt and fiber nib possibly taked has been provided with restriction.Another shortcoming then shows in the use of felt and fiber nib.In the useful life period of nib, felt may wear and tear and separate with filamentary material.Similarly, fiber possibly be dissolved in the ink solvent, makes the nib reduction, and further causes wearing and tearing.
In addition, containing the performance of the applicator of felt and fiber nib can be impaired because of the degeneration of felt and filamentary material.Wearing and tearing and other sepn processes can have a strong impact on the fineness of applicator, make its use become difficult.And fibrolysis possibly cause excessive ink dissipation and stream to leak in ink solvent, makes problem more complicated.
Consider foregoing problems and shortcoming, the material that has superior mechanical and chemical property and can be used as applicator need be provided.
In addition, the porousness macromolecular material has all obtained in a plurality of fields using and has brought into play and will act on emphatically.The porousness macromolecular material has been widely used in filtration and the fluid barriers application.Current filtration unit generally includes housing and is arranged in the macromolecular filtering medium on the fluid channel of running through housing.When fluid got into housing, it was through this filtration medium, so that the compsn in the fluid stream is removed.Said here fluid refers to gas, liquid or its combination.The effect of filtration unit depends on some factors, comprises keeping between itself and the housing fully by filtration medium sealing getting around the ability of filtration medium to stop fluid.
The fluid that gets around filtration medium can cause serious problem, especially when filtration medium during also as the barrier of selected fluid (like the aqueous solution).The fluid that gets around filtration medium may pollute downstream unit and technology, causes equipment to use inconvenience, corrosion and expensive maintenance.For example, pipette (pipette) generally includes filters or barrier media, and fluids such as this filtration or barrier media permission gas pass through, but can stop the liquid that can pollute pipette (pipette) to pass through.Get around and filter or the pipette that fluid polluted (pipette) of barrier media need be destroyed or decontamination usually, follow-up other solution are polluted preventing.
A shortcoming of current porousness macromolecular filtering and barrier media is that its character is hard, is difficult to fully seal with housing.When having, housing and/or filtration medium produce or during defective that packaging technology causes, and especially true.Therefore, when production includes the strainer that is arranged in the filtration medium in the housing, should keep accurate tolerance.Except filtration medium drops out housing or is arranged in the housing out of position, the requirement of precision tolerance is caused scrapping of large-tonnage product usually.
Consider foregoing problems, need provide and to form abundant sealing in case fluid gets around with housing, can not receive the filtration and the barrier media of the desired precision tolerance restriction of current straining installation again.
